Post Any way to make powerful bullets that don't destroy terrain?
Hello there, I've been a lurker around here for awhile but now I want to start modding.
I'm thinking of making some kind of sniper rifle strong enough to pierce through multiple people, but the gun only results in bullets that poke deep holes in concrete.
Is there any way to give a bullet good penetration against people but not terrain?

You can increase the mass of the round, while reducing sharpness to reduce terrain rape, but this can cause the actor to be pushed back when the weapon is fired. A good way to avoid the push effect is the have the weapon fire an emitter which then fires the particle of choice. See the Coalition Heavy Sniper rifle for an idea on how to do this.

I once did a rifle that fired an emitter, which it spawned a particle which had a mass of 5000 kg and a very, very low sharpness; it would pierce like 10 or 20 pixels of sand but it would crush through infinite enemies if enough space was given.

I'll see if I have it around and send it to you, you might find it useful.

Alternatively, increase the sharpness if an actor is in front of the bullet with lua

That is a very cool idea.

What would the lua code be for sharpening said bullet and then unsharpening them?

Here's what I do for lesser terrain damage: Start with regular sharpness, check for terrain in front of the bullet with a strength ray every update with a vector that's one third of the bullet's velocity, and switch to low sharpness if there is terrain there.

Instead of dividing by two, you could divide by a higher number for even less barrier penetration, or just set sharpness to 0 to not penetrate even grass.

Now that I think about it, though, this would lessen sharpness if the target had terrain very close behind it, or if the target was a door. It also doesn't nerf the bullet if you've got the muzzle pointing straight into the ground, because the bullet's already done some penetrating before the update function ever happens. So this is a far from ideal method.


This should be way better; still uses the initial sharpness at very first, though.
Code:
function Create(self)
   self.inaccuracy = 0 -- raise to reduce lag but decrease detection quality
   self.InitialSharpness = self.Sharpness --store original sharpness value
   self.TerrainModifier = 0.5 -- multiply the original sharpness by this for terrain penetration
   self.ObjectModifier = 1 --multiply the original sharpness by this for object penetration
end

function Update(self)
   local terrcheck = Vector(0,0);
   if SceneMan:CastMORay(self.Pos,(self.Vel / 3),0,0,true, self.inaccuracy) == 255 then
      self.Sharpness = self.InitialSharpness * self.TerrainModifier
   else
      self.Sharpness = self.InitialSharpness * self.ObjectModifier
   end
end

Code:
function Update(self)

local terrcheck = Vector(0,0);
   if SceneMan:CastStrengthRay(self.Pos,Vector(self.Vel.X,self.Vel.Y):SetMagnitude(16),0,terrcheck,0,0,true) then
            self.ToDelete = true;
     end

end


This Should work.
It's from a mod called Decimator i found somewhere
